Description

The invention is intended for heating food in extreme conditions, in particular for heating food at low temperatures and high humidity.

In 1897, the Russian engineer Fedorov was the first to propose the production of self-heating canned goods. In 1915, the Russian army began to receive them in the trenches. They were gratefully recalled in memoirs by General Shkuro, who was the first world commander of a plastun detachment on the Caucasian front. The Turkish rear was their permanent habitat, and this stew really helped them out.

A feature of this design was that only one can was heated, and even then it was uneven.

Subsequent constructions, which were manufactured all over the world, also provided for heating only one container with food or liquid, and also did not allow melt the snow for cooking and drinking and other household needs in winter conditions.

So, in self-heating packages “doy pack” there is a built-in button for starting internal interlayer heating mechanisms built into the package. That allows you to heat only the products and liquids of this package.

The company Hot-Can (hot can) from Malaysia, currently a leader in the manufacture of self-heating packages, produces products with the calculation of heating only one can.

The TREKMATES company (Great Britain) manufactures self-heating bags FCS03, which require complex manipulations to heat food, which makes it difficult to cook them under extreme conditions. Here is a way to use them:

- place food requiring warming up in a steel container;

- put the self-heating bag in a plastic container;

- fill the self-heating bag with water of 120 ml; put the steel container in a plastic container;

- close the lid and wait 7-10 minutes,

which also involves heating only one package.

AmeriQua, a company specializing in the supply of dry rations to the US Army, manufactures the A-Pack device, which provides for placing the main dish in a special package, which, in turn, must be inserted into a special package. Due to the chemical reaction between the bag and the package, heat is generated and the food heats up. This, in fact, is also the heating of one package and the complete absence of the possibility of heating other food and melting snow.

As the closest analogue, the technical solution described in the patent of the Russian Federation No. 2098996, publ. 12/20/1997, and which is a device for heating food, consisting of a housing, heating elements, containers for storing food and cooking. The disadvantages of the known device are the lack of the possibility of heating food in conditions of low temperatures and high humidity.

The objective of the present invention is to remedy the above disadvantages.

The technical result consists in ensuring the functioning of the device in extreme conditions of low temperatures and at high humidity, when it is difficult to use conventional heating devices, as well as in the absence of water in a liquid state.

The technical result is ensured by the fact that the device for heating food includes a housing, heating elements, containers for storing food and cooking. The device further comprises a heat insulating material, and also contains a heat-resistant container in which a heating element is placed and there is space for one canning container. In addition, food storage and cooking containers and heating elements are made of heat-resistant materials. At the same time, inside the heating elements are cellophane containers with salt water and quicklime. Two holes are made in the upper part of the heating elements, one of the holes is located above the cellophane container with salt water and makes it possible to break through the cellophane container with salt water peak. In addition, the holes are made with the possibility of gluing in order to avoid an uncontrolled reaction of slaking lime.

The essence of the present invention is illustrated by the following illustrations:

fig. 1 - heating element;

fig. 2 - a device for heating food.

The developed device provides for the possibility of preparing hot first courses, heating canned food and liquids, as well as melting snow to produce hot liquids due to the wide mouth of the container.

The heating element (Fig. 1) has the following design features.

It is made of heat-resistant and heat-conducting materials 1, because during the reaction of slaking lime, the temperature reaches more than 100 degrees. Inside the element there is a cellophane container with salt water (sodium chloride aqueous solution - NaCl) 6 and quicklime 7. The use of cellophane containers with salt water is due to the fact that the solution of sodium chloride in water has a lower freezing point than plain water.

On the top of the heating element are two openings: square 2 and rectangular 5 shapes. The rectangular shape is located above the salt water container and is designed to break through the container through it with a special peak 4 and begin the quenching reaction.

The resulting steam will exit from the rectangular hole 5.

In order to avoid uncontrolled extinguishing of lime, both holes 2, 5 are sealed with adhesive tape, which also fixes the peak on the end of the heating element.

In order to activate the heating element, it is necessary to remove the adhesive tape and remove the lance. In this case, square 2 and rectangular 5 holes are freed. Then enter the peak into the rectangular hole 5.

The device for heating food (Fig. 2) consists of the following elements:

- housing 8;

- heat insulating material 9;

- a container for storing products, consisting of two containers 10 made of heat-resistant and heat-conducting materials;

- the first heating element 11;

- heat-resistant and heat-conducting container 13, in which are located: the second heating element 14 and a place for a flat canning container 12.

The device for heating food is placed in a sealed bag.

The procedure for using the device for heating food:

- remove rations from sealed packaging;

- extract from the container 10 products;

- place the concentrate or sublimate of the first dish in it, fill it with water, and in its absence - compressed snow, ice;

- actuate the first heating element 11;

- after eating the first dish and the contents of the flat canning container from the container 10, remove the container in which the first dish was prepared, and also remove the spent first heating element 11;

- move the second heating element 14 to the container 10;

- pour water into the second container container 10 and container 13 container (place compressed snow, ice) and activate the heating element. The water heated in the second container of the container 10 can be used to make tea, coffee, energy drinks. In this case, you should remove the second container and drink a hot drink. Hot water from the container 13 can be used for other purposes.

This kind of design is especially relevant for use in extreme conditions of low temperatures and high humidity, when it is difficult to use conventional heating devices, and also there is no water in a liquid state. Manipulations with the actuation of this soldering in severe frost can be carried out with gloves or mittens.

In addition, heating elements can be used separately from soldering to heat users or heat objects.
